Green Options

Last week I wrote in this space that when faced with a problem that so clearly requires huge top-down action from governments the world over, what two contrarians write in a book doesn’t exactly bother me that much. But now members of Congress are pissed off too.

Because of their enormous body size, whales have been thought to contribute a considerable amount of carbon dioxide to the total greenhouse gas build-up whenever they exhale. However, Trish J. Lavery of Flinders University in Adelaide, Australia claims they – the sperms whales of Southern Ocean, at least – are falsely-accused and that they live quite a carbon-neutral life.

During the October 13 Biennial Conference on the Biology of Marine Mammals in Quebec City, Canada, Lavery talked about earlier calculations overlooking the whales’ capacity to offset their carbon dioxide emissions. The 210,000 sperm whales in Southern Ocean should be declared carbon neutral, according to Lavery. The carbon neutral status is achieved by bringing iron from the depths of the ocean to the surface whenever they feed. This extra iron in the water induces plankton growth which in turn traps carbon and prevents it from being released into the atmosphere.

Today all over the world people are rallying on behalf of Mother Nature. People are holding up signs, waving around banners with the numbers 350! What does 350 mean?

Scientists say that currently we are at 350 parts per million which is the safe limit for humanity. Currently we are at 387 parts per million; of carbon dioxide that has entered into the atmosphere!

Today’s message is about taking action and sending a message. This December the world’s leaders will meet [...]

Today is 350.org’s International Day of Climate Action, during which people around the world are trying to call attention to our need to bring the levels of carbon dioxide in the atmosphere back down to 350 parts-per-million (ppm). A noble cause, to be sure — but can we actually do it?

An analysis done by Biofuels Digest has come to the very surprising conclusion that an electric car will produce 30% more carbon dioxide emissions over its lifetime than a car powered by E85 corn ethanol. Not only that, the study also found that the same electric car will produce 21% more carbon dioxide than even a gasoline powered car.

These claims assume that 100% of the electricity for the EV comes from coal-fired power plants and that a comparable car would get 35 mpg—both of which seem like unrealistic assumptions. So I dug around the internet today to try and come up with more realistic numbers.

An archive of my Big Coal cartoons. The pen is mightier than the sword (but probably not as mighty as the multi-billion dollar coal industry…).

According to CO2isgreen.org (and .com and .net) all of this extra carbon pollution we are spewing is good for both us and the Earth! What luck! I’m getting a Hummer!

While carbon capture and sequestration technology remains controversial, studies to delve deeper into it are ongoing in hopes of presenting one way to alleviate emission levels. A team from MIT has been studying a carbon capture and sequestration (CCS) technique called pressurized oxy-fuel combustion. This process converts the carbon dioxide emissions of a power plant into a pressurized liquid stream meant to be pumped underground. Team leader Ahmed Ghoniem of MIT claims that his team is the only one conducting an academic study of “pressurized combustion system for carbon dioxide capture.”

Nitrous oxide, more commonly known at your dentist’s office as laughing gas, is now the most prevalent man-made substance damaging the ozone layer. And it’s a greenhouse gas. Sadly, the joke’s apparently on us.

The Department of Energy (DOE) announced today it will fund $27.6 million for next generation carbon capture methods using geologic storage. Suspiciously, this announcement follows on the heals of the State Department’s approval of a pipeline from Canada’s tar sands to the United States.

This picture is a picture of the beautiful Monterey, California coastline. This is where I grew up. It is famous for it’s beautiful sea life. Sea otters, jelly fish, sea lions, kelp forests all populate the Monterey coast.  The Pacific Ocean is the largest ocean in the world. Yet, with all that mass of water, we humans are changing the chemical properties. The acid levels in the pacific ocean, as well as every ocean around the world, are rising. If things keep going this beautiful coastline, my home, will become a wasteland of acid. Habitable to only the most extremophiles.

Rewind our story. Fossil fuels are not just a problem for our atmosphere. When we burn fossil fuels carbon dioxide falls down into the sea. The carbon dioxide is quickly converted into carbonic acid. Carbonic acid has been known to be corrosive to corals and shellfish, and now scientists are discovering that rising acid levels in the ocean are effecting other animals as well.
